An objecty ott-he invention is to -prvidenovel means for Checking .er retardingthe moveinent of the picker stick atthe .end vof its stroke-y Another Q bieet is ,to prei/idea c eek v for picker sticks that will prevent any bending or hammering f the seme, and which willprevent-the reb9und,

A further object is tn nrovid .a devicef .the kind ,described-for holding the picker ystick medially disposed -with relation to .thelavheanr- A more particu1ar-0hieetis theprvisipnof 1 -picker stick cheek .especially constructed for vlrelding the Picker stick under springtension end preventing rebounding and chatteringofihe pickerstick when it has reached its outward limit of movement.

Yet a further object vis to provide .a device ot the character described consivstsfn iimber of parts and which provides easy means of adjustment of the parte.

OtherA Objects will appear hereinafter throughout the Specification- Figure l -is a side elevational v iew .of the picker stick Cheek;

Figure 2 is abcttonl plan vi.e.w of. the cheekshown in Figure 1 with certain of the parts shown in section; and

Figure 3 is an end elevational view of the structure shown in Figures 1 and 2.

In the accompanying drawing, my improved checking device is attached to the lay of the loom, not shown, that is provided with the usual picker stick, and this device is attached to the underside of one or both ends of the lay of the loom. The numeral indicates a pair of supporting plates, or a single plate may be provided to take the place of said pair of plates. Said plates are provided with apertures 12 for attachment of the device to the underside of the lay. I prefer a pair of plates instead of a single plate for the purpose of regulating the relationship of the flat springs hereinafter described.

Each plate is provided with an upstanding boss 14 for mounting the main flat springs 16 whose inner sides are provided with pads of leather, rubber, or rubber-like material 18.

Means is provided for reinforcing and adjustably mounting the main ilat springs. The reinforcing means comprises outer reinforcing springs 20, and an inner rocking plate 22.

Each rocking plate is composed of spring metal and is provided with a substantially centrally located bulge or hump 24, as seen particularly in Figures 2 and 3.

Each of the springs 16 and 20, and the inner rocker plate 22 and boss 14 is provided with spaced apertures for the reception of the screw bolts 26 having squared heads 28. A washer 30 may be interposed between each head 2S and its outer reinforcing spring 20. Only the apertures in bosses 14 need be screw threaded, the corresponding e 2,719,539 iiatentea oct. 4, 1,955

apertures Ain the rocking plate 22 and springs 16 and 20 preferably .being Unthreaded apertures` Itwill be noted that each spring16 lcomprises awsubstantially straightfportion-34 substantially( parallel tothe Supportay and a portion 38 et an angle therete, therettions 38 converging toward each other to A form a V ,4 0,

1urther, t he ASpringe 20 eemprise straight, parallel pertenfel everlyineportions 34 0f Springs 16, and angled portions 36roverlying part of portions 38 of springs 16 t0 renferee Saidsprinas 16- By ,reference `tol 'the structuremparticularly 'shown A in Figure 2, it will be noted that tightening of the sc fC-W bolts IV26 will cause each unit including its setmof Springs and leather covers mounted thereon, to move toward eaeh, the.r The bulge in eaeh inner roeldns ,nl ate ifs gradually attened ae .the Serew bolts are tightenedend this-bulge forms a resilient or spring-like mounting for each unit, as well as a rocker.

Moreover, should it be desired to .changegthe angle of each unit to provide a larger or smaller V-shaped recess, this may be accomplished by loosening onerof the screw bolts of one unit slightly and tightening the other screw bolt of that unit. This adjustment will enable one to make a very accurate adjustment for the picker staff, which moves `into the V-shaped recess. This adjusting means is an important structural feature of the present invention. y

From the foregoing, it will be obvious that when the shuttleis thrown and comes in contact with the picker on the stall, said staffwill be forced into the V-Shaped opening 4t),to be gradually retarding the speed o f the shuttlenntilrit arrives at the end of Vits race. vThis cheek, therefore, obviates to a large extent the necessity of binders, and ,greatlyA reduces the wear on the shuttle.

y Accurate andeiective adjustment is assuredl by. the two Wfeye ef adjusting eeeh unit; i-Y e, the tightening. 91" loosening of both screw bolts 26 oneach unit. Altermately ene .Screw/ bolt may be tightened While the other ie allowed to remain untightened, or is moved in the opposite direction as the screw bolt of that unit. This latter action effects a rocking movement about the fulcrum of the bulge or raised portion 24.

The above description and drawings discloses a single embodiment of the invention, and specific language has been employed in describing the several iigures. It will nevertheless be understood that no limitations of the scope of the invention are thereby contemplated, and that various alterations and modications may be made such as would occur to one skilled in the art to which the invention relates.
